id0102j5149700

DTC P1589:00

Intake shutter valve circuit range/performance problem

DETECTION CONDITION
•  With the following conditions met, the difference between the target intake shutter valve opening angle and the actual value exceeds 4.2 °for a continuous 2 s.
―  Battery voltage: 8—16 V
―  0.5 s have elapsed after ignition is switched ON (engine off or on)
―  The following DTCs are not detected
•  Constant voltage power supply control system: P0653:00, P0652:00
•  Intake shutter valve position sensor: P0122:00, P0123:00
•  Intake shutter valve control system: P2101:00
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Limits engine torque.
•  Inhibits the automatic diesel particulate filter regeneration control.
•  Inhibits the intake shutter valve control.
•  Inhibits the manual diesel particulate filter regeneration control.
•  Inhibits the EGR control.
•  Inhibits engine-stop by i-stop control.
POSSIBLE CAUSE
•  Intake shutter valve connector or terminal malfunction
•  Short to ground in wiring harness between intake shutter valve terminal B and PCM terminal 1AX
•  PCM connector or terminal malfunction
•  Intake shutter valve malfunction
―  Intake shutter valve sticking, poor operation
―  Intake shutter valve frozen
―  Intake shutter valve foreign matter penetration
•  Intake shutter valve position sensor malfunction
•  PCM malfunction


Diagnostic Procedure

Step

Inspection

Results

Action

1
RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the freeze frame data/snap shot data.
Go to the next step.
2
VERIFY OTHER RELATED DTCs
•  Switch the ignition OFF, and then switch it ON (engine off).
•  Display the DTCs using the M-MDS.
•  Has any DTC other than P2118:00 been stored?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
Go to the next step.
3
INSPECT INTAKE SHUTTER VALVE POSITION SENSOR
•  Reconnect all the disconnected connectors.
•  Inspect the intake shutter valve position sensor.
•  Is the intake shutter valve position sensor normal?
Yes
Go to the next step.
No
Replace the intake shutter valve position sensor, then go to Step 9.
4
INSPECT INTAKE SHUTTER VALVE CONNECTOR CONDITION
•  Switch the ignition OFF.
•  Disconnect the intake shutter valve connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
5
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
6
INSPECT INTAKE SHUTTER VALVE CONTROL CIRCUIT FOR SHORT TO GROUND
•  Verify that the intake shutter valve connector is disconnected.
•  Inspect for continuity between intake shutter valve terminal B (vehicle wiring harness side) and ground.
•  Is there continuity?
Yes
Refer to the wiring diagram and verify if there is a common connector between intake shutter valve terminal B and PCM terminal 1AX.
If there is a common connector:
•  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location.
•  Repair or replace the malfunctioning location.
If there is no common connector:
•  Repair or replace the wiring harness which is shorted to ground.
Go to Step 9.
No
Go to the next step.
7
INSPECT INTAKE SHUTTER VALVE
•  Inspect the intake shutter valve.
•  Is the intake shutter valve normal?
Yes
Go to the next step.
No
Replace the intake shutter valve, then go to the Step 9.
8
INSPECT INTAKE SHUTTER VALVE FOR FOREIGN MATTER
•  Remove the intake shutter valve.
•  Inspect the intake shutter valve for foreign matter.
•  Is there foreign matter in the intake shutter valve?
Yes
Remove the foreign matter from the intake shutter valve, then go to the next step.
No
Go to the next step.
9
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Reconnect all the disconnected connectors.
•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
•  Drive the vehicle on flat roads under the following conditions 5 times repeatedly.
1.  Idle the engine for 20 s.
2.  Accelerate in 2nd gear to 35 km/h and drive the vehicle while maintaining the speed for 25 s.
3.  Stop the vehicle and idle the engine for 20 s.
4.  Accelerate in 3rd gear to 50 km/h and drive the vehicle while maintaining the speed for 50 s.
5.  Stop the vehicle and idle the engine for 20 s.
•  Stop the engine.
•  Display the DTCs using the M-MDS.
•  Has DTC P1589:00 been recorded?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM, then go to the next step.
No
Go to the next step.
10
VERIFY OTHER DTCs
•  Has any other DTC or pending code been stored?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
